Is it for you?
We have not ridden this bike. This read is based on the spec sheet and Australian seller information, not a test ride.
Best suited to
Apartment dwellers and multi-modal commuters who want a proper Bosch mid-drive in a folder that fits under a desk or in a train luggage bay.
Standout strength
Bosch mid-drive in a true folding bike is rare. The S10 delivers real mid-drive performance in a compact package.
The main compromise
The 20-inch wheels mean a different ride feel than a full-size bike. Takes a ride or two to adapt.
Consider something else if
You want the lightest possible folder. The Brompton Electric is lighter but costs more.

Common questions
How much does the Tern Vektron S10 cost in Australia?
The Tern Vektron S10 is listed at $4,999 (ride-away). eBikeFinder checks pricing against manufacturer and distributor information, and prices can change with sales and stock.
Is the Tern Vektron S10 road legal in Australia?
Yes. The Tern Vektron S10 is a 250W pedal-assist e-bike that stops assisting at 25 km/h, which meets the road-legal e-bike standard in every Australian state. Compliance is asserted by the brand rather than independently verified, so confirm the current spec with the seller.
What is the range of the Tern Vektron S10?
The Tern Vektron S10 has a claimed range of 50 to 80 km from its 400Wh battery. Real-world range is usually lower than the claim, since it depends on assist level, rider weight, terrain and wind.
What motor does the Tern Vektron S10 have?
The Tern Vektron S10 uses a Bosch Active Line Plus motor, in a mid-drive position, producing 50Nm of torque. Mid-drive motors climb hills better because they work through the bike's gears.
How much does the Tern Vektron S10 weigh?
The Tern Vektron S10 weighs about 20.4 kg. That matters if you need to lift it onto a car rack, carry it up stairs, or store it, since e-bikes are heavier than regular bikes because of the motor and battery.
Who sells and backs the Tern Vektron S10 in Australia?
The Tern range is distributed in Australia by 99 Bikes and independent dealers. It comes with a 2 years frame, 2 years motor and battery warranty. Buying from a brand with real Australian support matters most when something needs a warranty claim or a service.
